Application nled March 4, 1926. uSerial No. 92,2557.

This invention relates to a motor vehicle, and has reference'more particularly to the type of suspension illustrated in Patent No. 1,515,716, November 18, 1924,1n which a conaxle and at its opposite end to the frame through a rubber block having rib and groove connection with the connectin arm and frame and rigidly clamped there etween.

The object of this invention`1s to atord a stronger and more rigid chassis construction through the use of a tubular cross member atv a point of the frame where maximum stliness is needed, such cross member serving as a support for the stationary section otthe rubber block housing and also as a bearlng forthe movable section which is part of or-rigidly connected to the forward end 'of the connecting arm.. t

A further purpose of the inventlon 1s to provide `a construction such that the stationary section of the rubber block housmg functions in the additional capacity of a tying means between the side and cross members of the frame, the cross member acting to support i the front end of the connecting argn and to center it and the rubber block with reference to the stationary housing section.

To these and other ends, the invention comprises the construction and arrangement that will appear clearly rom the following description when read in con] unction with the accompanyingr drawing, the novel fea-l tures being pointed out inthe claims following the description. f In the drawing: t Figure l is a side elevation of a portion of a motor vehicle frame showing a referred embodiment of the linvention applie thereto; Figure 2 is a plan view Figu 3--3 of Figure 1, and J Figure i is a sectional viewion line 1 -4 ofy Figure 3, y,

Reerring more partlcularl to the draw ing, in which like reference c aracters refer to correspondin parts throughout the several views, 1 designates the side members of a 'motor vehicle frame, 2 is the rear axle, and 3 is a cross member, preferably tubular, and

extending through openmgsr in the side members 1 as shown in Figure 3. The cross member 3 is preferabl located at the portion of at one end to anre 3 is a vertical sectional view on line' the frame shown, orwardly of the axle, wherev extreme stii'nessis needed, although it may be otherwise disposed if preferred.-

Mounted on the tubular cross member 3 is a i rigidly or otherwise connected to the axle 2.

The housing section 5 is journalled upon the tubular cross member 3 to permit of relative turning thereon, although the cross member may be otherwise constructed to afford a bearing for the movable housin section. 7 deslgnates a rubberblock forme on opposite sides with ribs and grooves engaging with correspondingly ribbed and grooved stamped metal plates which are rigidly secured to the inner surfaces of the housing sections 4 and 5. The housing section 5, or front end of the connecting arm 6, is held in clamping relation with the rubber block 7 by means of a nut 8a threaded on the tubular'housing 3 and acting to grip the rubber block 7 tightly between the stationary housing section 4L and the relatively movable housing section 5.

pression of the rubber block can be regulated, and likewise the resistance of the rubber to relative movement ofthe parts. The section carries a iange 9 that closely embraces the tubular cross member l3, to effect a snug fit between these parts-and prevent looseness or noise due to turning of the section 5. When relative movement occurs be-y tween the axle and frame, a slight turning of the housing section 5 takes place on the cross member '3, the arts being restored to normal relationship lby theresistance and stiffness of the ribs in rubber block 7. lit will be seen that the rubber block "together with the corrugated members forms a resilient torque-resisting'construetion for opposing the tendency of the arm v6 to rotate about the cross piece 3. The rubber block assembly just described as'mounted ,outsider the side members of theframe 'may also be arranged between the side members, if desirecl.

While the 'invention has been described with reference to a particular'construction, it isnot conned tothe precise details herein By adjusting the nut 8, the extent of com-- los shown, and this application is intended to, cover such modiications or departures as may come within the purposes of the improvement or the scope .of the following claims.

I claim:

1. In a motor vehicle, the combination with an axle and :trame having side members, of a cross member extending beyond thesides of said sidemembers, a housing comprising a stationary section ixedly mounted on and a movable section journalled on said cross member, a rubber block clamped between and having rib and groove connection with said housing sections, and an arm rigidly united to said movable section and having its outer end connected to the axle.

2. In a motor vehicle, the combination with an axle and frame having side members, vof a tubular cross member extendingv beyond the sides of said side members, a housing comprising a movable section journalled on said tubular cross member, a stationary housing section, a rubber block clamped between and havingriband groove connection with said housing sections, and anarm rigidly united to said movable section and having its outer end eonnected'tothe axle.

-3. AIn a motor vehicle, the combination with an axle and, frame having side members, of a tubular cross member extending beyond the sides of said side members and being restrained against rotation relative to said frame, a housing comprising relatively movable sections, a rubber block having rib and groove connection with and clamped between said sections, said cross member extending centrally through said sections and rubber block, one-of the sectionsbeing fixed and the other turning on said cross member, and.

an arm rigidly united with saidl movable section and having its outer end connected to l the axle.'l

4. In a motor vehicle, the combination with an axle and frame including a side member having an opening therethrough, of a tubular cross member extending through said opening, a housingcomprising a stationary section mounted on said tubular'cross member adjacent tothe side member and rigidly secured to both said side member and cross member, a movable housing section journalled on the tubular member, a rubber block clamped' between and having rib and groove connection with said housing sections, and an arm rigidly united to said movable section and having its outer end connected to the axle.

5. In a motor vehicle, the combination with an axle and frame including a side member having an opening therein, of a tubular cross member extendingv through saidl opening, a housing comprising relatively movable sections, a rubber block havingrib and groove connection with and clamped between said sections, the cross member extending centrally through said sections and rubber block, one of the sect-ions being rigidly secured to the side and cross members and the other turning on the cross ymember, means threaded von the cross member for engaging the movable yhousing section to clamp the rubber block, and an arm rigidly united'with said movable section andhaving its outer end connected to the axle.

' 6. In a motor vehicle including a frame and an axle, a mechanism for supporting said'rame from said axle comprising a transverse member extending entirelyacross said frame and connected thereto, a plurality of arms attached -at one end to said axle, the other ends of said arms being loosely mounted upon said transverse, member, and torqueresisting means operatively interposed between said transverse member and said arms. In witness whereof, I have hereunto signed my name. i
